This invention relates to a tool for trimming soft material, and isparticularly useful in cutting rubber tire and tube patches from sheetmaterial and in bufling or abrading the portion of a tube to which it isto be applied, although certain features of the invention are applicableindividually to other uses.

rlhe principal purpose of the invention is to provide a tool of thecharacter described which is of simple and substantial construction,which may be produced at a comparatively low cost and of a minimumamount of material, and which is highly efficient and convenient in use.Other objects and desirable features of the invention will appear in thecourse of the following description of an illustrative embodiment of theinvention.

In the accompanying drawings forming part of this specification, inwhich like numbers of reference denote like parts wherever they occur.

Figure 1 is a perspective view of one form of a tool made in accordancewith this invention;

Figure 2 is a. View of the bottom side of the same;

Figure 3 is a longitudinal vertical central sectional view of the same;

Figure 4 is a transverse sectional view of the same as it appearswithout the handle, looking toward the cutting blade;

Figures 5 and 6 are a plan and a bottom view, respectively, of amodification; and

Figure 7 is a lateral edge view of still another form of the invention.

A trimming sleeve 1 is formed by bending the opposing edges 2 of a metalsheet, preferably steel, towards one another, there being preferably twoconsecutive right angle bends employed in turning each edge, so that thesleeve is substantially oblong in cross-section, with the opposing edges2 in abutting relation to one another, and having a. rear side 4, frontside 5, and narrow or edge sides 6, with f the edges 2 on the rear side4c. A blade portion 7 of the sheet projects from the anterior. end 8 ofthe sleeve on the front side 5, the said blade 7 extending forwardly andobliquely across the opening at said end. A handle or body 9, shown inFigures l to 4, inclusive,

preferably of wood, and oblong incross sec"-` tion so as to' fitfrictionally inthe sheath or sleevel, is limitedin its forward movementthrough the sleeve by abutment against thev flange. orblader7.-Thisfunctioningof thev blade?? as a'stop for the handle 9 is especiallydesirable,for the'reason that, when the tool is in use, vthe pressureonk the handle is exerted toward the blade 7, and tends to'force thehandle through the sleeve, although the friction between the handleandthe sleeve is suficientto prevent the handle fromslipping out of thesleeve in the opposite direction. The blade is disposed obliquely withrespect /to theaxis of the sleeve for the further reason also that itassumes the proper operative position when the handle is held in itsmostconvenient position jfor cutting a beveled edge. For thev same reason,the front or cutting edge 10 of the blade is disposed obliquely, insteadof ata right angle to the axis of the sleeve. The handle 9 has itslfreeend 11 preferably covered with va deposit Vof abrasive material 12,such as `carborundum,`iso that it maybe usadas a buffer o r burnisherif'desired, to smooth the portionof the tube to which the patch is to beapplied. Notches or recesses 13'are formed inthe handle 9 to fit thefingers ofthe user so that it may be conveniently and securelyheld,especially when the end 11 is used Ias a' burnisher.y c

The abrasive material 12, however, cannot beused very effectivelyv on awetl surface, so that the frOntsideof the sleeve has been provided'witha plurality of'perforations 14, having outwardly bent edges 15 ,that maybe scraped over thezsurface to' be smoothed in grater-like fashion. 'i zIf desired, thehandle 9 may be dispensed with, andthe sleeve 1lengthened suliicie'ntly to serve'asa handle, the Aoutwardly dentedperforations 14 preferably extending along the full length of theelongated front face 5 of the sleeve, thereby expediting the bufling orsmoothing, especially where the surface to be smoothed is extensive.Figures 5 and 6 illustrate a form of the invention having an elongatedsleeve of this character. If, instead of cutting the patch with abeveled edge, it is preferable to cut it through 'GG coi at right anglesto the plane of the sheet of the patch, the form of the invention shownin Figure 7 may be employed, in which the blade extends from the sleevein parallel relation thereto, instead of obliquely.

Having thus fully described this invention, I hereby reserve the benefitof all changes in form,farrangement, order, of use ofparts, as it isevident that many minor changes may be made therein without departingfrom the spirit of this invention or thelscopel of'l the followingclaims.

I claim:

l. A cutter including asleeve, a blade projecting forwardly from theanterior end of saidsleeve and angularly withfrespect tofthe front `sidethereof, said bl-ade :presenting-a cutting edge disposed obliquelyacross the entire-opening at said end and a-handleinserted linto saidsleeve vwith its anterior end in= abutting relation tothe obliqueportionof saidfblade aclj,acentgsaidsleeve, whereby-said handle is preventedfromV slipping forwardly in said sleeve. Y

2. A cutter comprising a-sleeve-adaptedto be associated with a handle, ablade formed integrally therewith and projectingafrom one end ofsaidsleeve,- saidfbladeipresenting a cut-l tingedgey disposed obliquelytothe axis `of the y. sleeve, onel endof said cutting ,edge beingpositioned adjacentone side of said sleeve, the other end terminatingwithinthe-plane4 of the other side of said sleeve, said-blade being bentupwardly acrossfthe frontopeningzof said 4sleeve to engage the endofahandle inserted in said sleeve and. to. limit the forward travel. ofthefhandleiwhen pressure is applied thereto.

y3. -Ay cutter formed-from aasingle piece of material having la pair ofopposing edges bent towards one-another into lsleeve formation, a. bladeformed integrally therewith .and projecting from one end oflsaidvsleeve,.sad blade presenting a v-cutting edge disposed obliquely toAthe .axis off the` sleeve, one-end of said cutting edge being positionedadjacent one sidel of vsaidv sleeve, the otherA end; terminating'iwithinthe plane oftheother side of said sleeve, Ysaid -blade being bentupwardly acrossfthe Vfront openingr of-said sleeve tof engagethe end ofa handle inserted insaid-sleeve Y andrto limitthei forward. travel of`the vhandle when pressure is applied thereto.
